First of all, you need to define an array that contains 1 for the expanded modes and 0 otherwise, where the array index corresponds to the mode number. Then you may issue “mxpand, %arrname% and this should reduce results file quite a lot. Lastly, I recommend that you carefully review downstream harmonic/random vibration results as fewer modes will be used to do MSUP. I’ve created an example for your reference and let me know if you have any questions.
